ADAINV (Creating, Removing And Verifying Inverted Lists)

This document describes the utility "ADAINV".

The following topics are covered:

Functional Overview

The inverted list utility ADAINV creates, removes and verifies inverted lists for loaded files in a database. It does not require the Adabas nucleus to be active. The nucleus may, however, be active or shut down while ADAINV is running. The following functions are available:

  • The INVERT function establishes new descriptors;

  • The REINVERT function performs an implicit RELEASE and INVERT;

  • The RELEASE function removes existing descriptors;

  • The RESET_UQ function removes the unique status from descriptors;

  • The SET_UQ function establishes a unique status for existing descriptors;

  • The SUMMARY function displays the descriptor space summary for the specified descriptors and the required sizes to process these descriptors;

  • The VERIFY function checks the integrity of inverted lists.

A LOB file can only be specified for the functions REINVERT, SUMMARY and VERIFY.

These functions are mutually exclusive and only one of them may be executed each time this utility is run.

Notes:

  1. When you perform ADAINV INVERT or REINVERT for a collation descriptor, the collation descriptor is always created using the highest ICU version supported (for Adabas Version 6.5: ICU 5.4, for older Adabas versions: ICU 3.2).
  2. If you reinvert a collation descriptor created with ICU version 3.2 in order to upgrade to ICU version 5.4, there may be differences in the syntax or semantics of the collation specification. For example, with ICU version 3.2, the locale ‘fr’ implies the FRENCH option, while with ICU version 5.4, the FRENCH option must be specified explicitly. In such a case, instead of performing ADAINV REINVERT, first perform ADAINV RELEASE for the collation descriptor and then ADAINV INVERT with a new specification, which is equivalent to the old ICU version 3.2 specification.

When ADAINV is performed in online mode, Adabas users accessing the file may be active when ADAINV is running:

Function ACC Users UPD Users
INVERT Yes No
REINVERT No No
RELEASE No No
RESET_UQ Yes No
SET_UQ Yes No
SUMMARY Yes Yes
VERIFY Yes No

An Adabas user is an ACC user if he has only performed read or search operations for the file, or if he has executed an appropriate Open command. He is an UPD user if he has also performed insert, update or delete operations for the file or placed an ISN of the file in exclusive hold status, or if he has executed an appropriate open command.

If there are users of the file that are not permitted, as defined in the table shown above, ADAINV fails with an error ADA048.

Notes:

  1. An UPD user remains an UPD user after the end of the current transaction until the end of the user session.
  2. You can determine which users are currently accessing a file with the ADAOPR DISPLAY=UQ_FILES command.

If the utility writes records to the error file, it will exit with a non-zero status.

This utility is a single-function utility.

    VERIFY = number,
             {ALL_FIELDS | FIELDS {descriptor_name | FDT}, ...  [END_OF_FIELDS]}
D            [,ERRORS = number] 
             [,FDT] 
D            [,LWP = number[K|M]]

DBID

DBID = number

This parameter selects the database to be used.

INVERT

INVERT = number,
         FIELDS {field_name [,UQ] [,TR] | derived_descriptor_definition | FDT},
          ... [END_OF_FIELDS]
         [,FDT] 
         [,LWP = number[K|M]] 
         [,UQ_CONFLICT = keyword]

This function establishes new elementary, sub-, super-, hyper-, phonetic and collation descriptors at any time after a file has been initially loaded. `number' specifies the file containing the fields to be inverted. You are not allowed to specify the number of a LOB file.

FDT

This parameter displays the FDT of the selected file. This option may be specified before or within the field specification list.

FIELDS {field_name [,UQ] [,TR] | derived_descriptor_definition | FDT}, ... [END_OF_FIELDS]

This parameter specifies fields to be inverted. It can contain one or more

  • field name,

  • phonetic descriptor or

  • sub-, super-, hyper- or collation descriptor

specifications, each starting on a separate line. See Adabas Basics, FDT Record Structure for valid specifications of field names, phonetic, sub-, super-, hyper- or collation descriptors.

The options UQ and TR are used to specify whether the field in question is a unique descriptor or whether index truncation will be performed. See Adabas Basics, Definition Options for further information about the UQ and TR options.

Note:
Only fields for which the values are stored in the base file can be used as descriptors or parent fields of derived descriptors. For this reason, an invert function will be aborted if a field to be inverted or a parent field of a derived descriptor to be created has the LA or LB option and values are stored in the LOB file. LA and LB fields can be used as descriptors or parent fields of derived descriptors, but then all values are limited to 16 KB – 3, and the base record including these LA or LB field values must fit into one data block.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

LWP = number[K|M]

For the sort of descriptor values, ADAINV uses a work pool in memory. The default size of the work pool in most cases results in an optimal performance for ADAINV. The LWP parameter allows you to increase the work pool; it defines the additional space added to the default work pool size in bytes, kilobytes (K) or megabytes (M).

Increasing the work pool size may be useful in the following cases:

  • If you notice that in your environment the performance is better with a large work pool.

  • If the SORT container is too small for sorting the descriptor values; an adequate LWP parameter can decrease the required size of the SORT container.

You can use the SUMMARY function to determine the required value for this parameter.

UQ_CONFLICT = keyword

This parameter determines which action is to be taken when duplicate values are found for a unique descriptor. `keyword' may take the values ABORT or RESET. If ABORT is specified, ADAINV terminates execution and returns an error status if duplicate UQ descriptor values are found. If RESET is specified, the UQ status of the descriptors in question is removed and processing continues.

The default is UQ_CONFLICT = ABORT.

[NO]LOWER_CASE_FIELD_NAMES

[NO]LOWER_CASE_FIELD_NAMES

If LOWER_CASE_FIELD_NAMES is specified, Adabas field names are not converted to upper case. If NOLOWER_CASE_FIELD_NAMES is specified, Adabas field names are converted to upper case. The default is NOLOWER_CASE_FIELD_NAMES.

This parameter must be specified before the FIELDS parameter.

REINVERT

REINVERT = number,
           {ALL_FIELDS | FIELDS {descriptor_name | FDT}, ...  [END_OF_FIELDS]}
           [,FDT] 
           [,[NO]FORMAT]
           [,LWP = number[K|M]]
           [,UQ_CONFLICT = keyword]

This function performs an implicit RELEASE and INVERT. This reduces the probability of a typing error, especially for sub- and superdescriptors.

Note:
The purpose of ADAINV REINVERT is to recreate a descriptor if the index tree becomes unbalanced as a result of a large number of updates, or if an index error occurred. Descriptors are always recreated with the same definition as before; if you want to change the definition of a descriptor, for example a superdescriptor, you must perform ADAINV RELEASE followed by ADAINV INVERT with the new descriptor definition.

ALL_FIELDS

This parameter specifies that all descriptors of the selected file are to be released/inverted.

FDT

This parameter displays the FDT of the selected file. This option may be specified before or within the fields specification list.

FIELDS {descriptor_name | FDT}, ... [END_OF_FIELDS]

This parameter specifies the descriptors to be released/reinverted. It can be followed by one or more field names, each starting on a separate line. See Adabas Basics, FDT Record Structure for a description of valid field name specifications.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

[NO]FORMAT

If a descriptor is released or reinverted, the new index created is generally smaller than the old index and requires less disk space. The FORMAT option can be used to format the blocks that are no longer used by the index but which are still allocated to the file.

The default is NOFORMAT.

LWP = number[K|M]

For the sort of descriptor values, ADAINV uses a work pool in memory. The default size of the work pool in most cases results in an optimal performance for ADAINV. The LWP parameter allows you to increase the work pool; it defines the additional space added to the default work pool size in bytes, kilobytes (K) or megabytes (M).

Increasing the work pool size may be useful in the following cases:

  • If you notice that in your environment the performance is better with a large work pool.

  • If the SORT container is too small for sorting the descriptor values; an adequate LWP parameter can decrease the required size of the SORT container.

You can use the SUMMARY function to determine the required value for this parameter.

UQ_CONFLICT = keyword

This parameter determines which action is to be taken when duplicate values are found for a unique descriptor. `keyword' may take the values ABORT or RESET. If ABORT is specified, ADAINV terminates execution and returns an error status if duplicate UQ descriptor values are found. If RESET is specified, the UQ status of the descriptors in question is removed and processing continues.

The default is UQ_CONFLICT = ABORT.

RELEASE

RELEASE = number,
          {ALL_FIELDS | FIELDS {descriptor_name | FDT}, ...  [END_OF_FIELDS]}
          [,FDT] 
          [,[NO]FORMAT]

This function removes elementary, sub-, super-, hyper-, phonetic and collation descriptors from the file specified by `number'. You are not allowed to specify the number of a LOB file.

ALL_FIELDS

This parameter specifies that all descriptors of the selected file are to be released.

FDT

This parameter displays the FDT of the selected file. This option may be specified before or within the fields specification list.

FIELDS {descriptor_name | FDT}, ... [END_OF_FIELDS]

This parameter specifies the descriptors to be released. It can be followed by one or more field names, each starting on a separate line. See Adabas Basics, FDT Record Structure for a description of valid field name specifications.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

[NO]FORMAT

If a descriptor is released or reinverted, the new index created is generally smaller than the old index and requires less disk space. The FORMAT option can be used to format the blocks that are no longer used by the index but which are still allocated to the file.

The default is NOFORMAT.

RESET_UQ

RESET_UQ = number,
           {ALL_FIELDS | FIELDS {descriptor_name | FDT}, ...  [END_OF_FIELDS]}
           [,FDT]

This function removes the unique status from elementary, sub-, hyper-, super- and collation descriptors defined in the file specified by `number'. You are not allowed to specify the number of a LOB file.

ALL_FIELDS

This parameter specifies that the unique status is to be removed from all unique descriptors in the specified file.

FDT

This parameter displays the Field Definition Table (FDT) of the selected file. This option may be specified before or within the fields specification list.

FIELDS {descriptor_name | FDT}, ... [END_OF_FIELDS]

This parameter specifies the descriptors that are to have unique status removed. It can be followed by one or more field names, each starting on a separate line. See Adabas Basics, FDT Record Structure for a description of valid field name specifications.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

SET_UQ

SET_UQ = number,
         {ALL_FIELDS | FIELDS {descriptor_name | FDT}, ...  [END_OF_FIELDS]}
         [,FDT]
         [,UQ_CONFLICT = keyword]

This function establishes the unique status for elementary, sub-, hyper-, super- and collation descriptors defined in the file specified by `number'. You are not allowed to specify the number of a LOB file.

ALL_FIELDS

This parameter specifies that the unique status is to be established for all elementary, sub-, hyper-, super- and collation descriptors defined in the specified file.

FDT

This parameter displays the FDT of the selected file. This option may be specified before or within the fields specification list.

FIELDS {descriptor_name | FDT}, ... [END_OF_FIELDS]

This parameter specifies the descriptors for which the unique status is to be established. It can be followed by one or more field names, each starting on a separate line. See Adabas Basics, FDT Record Structure for a description of valid field name specifications.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

UQ_CONFLICT = keyword

This parameter determines which action is to be taken when duplicate values are found for a unique descriptor. `keyword' may take the values ABORT or RESET. If ABORT is specified, ADAINV terminates execution and returns an error status if duplicate descriptor values are found. If RESET is specified, the UQ status of the descriptors in question is not established and processing continues.

The default is UQ_CONFLICT = ABORT

SUMMARY

SUMMARY = number, 
          {ALL_FIELDS | FIELDS 
          {descriptor_name | derived_descriptor_definition | FDT},
           ...  [END_OF_FIELDS]}
          [,FDT]
          [,FULL]

This function displays the descriptor space summary (DSS) for the specified descriptors and the required sizes to process the descriptors.

Note:
Processing the exact size would be too complicated. It may be that sizes a little smaller than those displayed are sufficient. If the file is updated during or after the SUMMARY function, the displayed values might also be too small.

See Adabas Basics, Optimization of ADAMUP and ADAINV Processing for further information about ADAINV SUMMARY processing.

ALL_FIELDS

This parameter specifies that all descriptors of the selected files are to be checked.

FDT

This parameter displays the FDT of the selected file. This option may be specified before or within the fields specification list.

FIELDS {descriptor_name | derived_descriptor_definition | FDT}, ... [END_OF_FIELDS]

This parameter specifies the descriptors for which the unique status is to be established. It can be followed by one or more field names, phonetic descriptors, subdescriptors, superdescriptors, hyperdescriptors or collation descriptors, each starting on a separate line. You can specify fields that are descriptors or fields that are not descriptors. See Adabas Basics, FDT Record Structure for a description of valid field name specifications.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

FULL

If this is specified, each descriptor is displayed along with the sizes that are required for the descriptor. This can be helpful if not all of the specified fields are to be processed.

VERIFY

VERIFY = number,
         {ALL_FIELDS | FIELDS {descriptor_name | FDT}, ...  [END_OF_FIELDS]}
         [,ERRORS = number] 
         [,FDT] 
         [,LWP = number[K|M]]

This function checks the integrity of inverted lists of the file specified by `number'.

ALL_FIELDS

This parameter specifies that all descriptors of the selected file are to be checked.

ERRORS = number

This parameter specifies the number of errors that have to be reported in order to terminate the verification of a descriptor.

The default is 20.

FDT

This parameter displays the FDT of the selected file. This option may be specified before or within the fields specification list.

FIELDS {descriptor_name | FDT}, ... [END_OF_FIELDS]

This parameter specifies the descriptor fields to be verified. It can be followed by one or more field names, each starting on a separate line. See Adabas Basics, FDT Record Structure for a description of valid field name specifications.

If the field definitions are terminated with the END_OF_FIELDS parameter, this parameter must be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used. In addition, the FDT parameter must also be specified in upper case when the LOWER_CASE_FIELD_NAMES parameter is used.

LWP = number[K|M]

For the sort of descriptor values, ADAINV uses a work pool in memory. The default size of the work pool in most cases results in an optimal performance for ADAINV. The LWP parameter allows you to increase the work pool; it defines the additional space added to the default work pool size in bytes, kilobytes (K) or megabytes (M).

Increasing the work pool size may be useful in the following cases:

  • If you notice that in your environment the performance is better with a large work pool.

  • If the SORT container is too small for sorting the descriptor values; an adequate LWP parameter can decrease the required size of the SORT container.

You can use the SUMMARY function to determine the required value for this parameter.

Restart Considerations

ADAINV has no restart capability. However, it may or may not be possible to re-start an abnormally terminated ADAINV from the beginning.

If ADAINV terminates abnormally, it can usually be restarted from the beginning. However, if ADAINV has modified the index, the following points have to be considered:

  • The function REINVERT ... FIELDS is the same as the function RELEASE ... FIELDS followed by the function INVERT ... FIELDS. So if ADAINV has aborted in the INVERT phase, perform the function INVERT ... FIELDS to restart the operation.

  • If ADAINV is performed offline, there is a very small amount of time where a few records that together form a logical unit are written to disk. If ADAINV terminates after the first of these records has been written and before the last has been written, ADAINV cannot be restarted. In this case, the function REINVERT ... ALL_FIELDS is required. This cannot happen if ADAINV is performed online.

  • If ADAINV terminates abnormally, it can happen that some index blocks are lost. These index blocks can only be recovered by the function REINVERT ... ALL_FIELDS or by using the utility ADAORD or by using the utilities ADAULD and ADAMUP.

Examples

Example 1

adainv: dbid=1
adainv: invert=10, fields
adainv: HO

The elementary field HO in file 10 of database 1 is inverted.

Example 2

adainv: dbid=1
adainv: invert=10
adainv: lwp=600k
adainv: fields
adainv: ph=phon(na)
adainv: sp=na(1,3),yy(1,2),uq
adainv: bb,uq

Three new descriptors are established for file 10 in database 1. PH is a phonetic descriptor based on the field NA. SP is a unique superdescriptor derived from bytes 1 to 3 of field NA and bytes 1 to 2 of field YY. The elementary field BB is changed to descriptor status and the unique flag is set. The size of the work pool to be used for the sort is increased to 600 K.

Example 3

adainv: dbid=1
adainv: release=10
adainv: fields
adainv: ho
adainv: ph

The two descriptors HO and PH from the examples above are released.

Example 4

adainv: dbid = 1, verify = 10
adainv: errors = 5
adainv: fields
adainv: sp
adainv: na
adainv: end_of_fields

The descriptors SP and NA are verified. The descriptor value table entries generated for descriptor NA are checked against the decompressed values of this field. Verification is terminated if more than five errors are reported for each descriptor.

Example 5

adainv: dbid = 1, reinvert = 10
adainv: fields
adainv: na

The descriptor NA in file 10 of database 1 is to be reinverted (this may be necessary if errors are reported in example 4).

Example 6

adainv: db=12
adainv: reinvert=9
adainv: all_fields

The complete index is recreated for file 9 in database 12.

The following output is produced: 

%ADAINV-I-FILE, file 9, EMPLOYEES

%ADAINV-I-IOCNT,         85 IOs on dataset DATA
%ADAINV-I-IOCNT,         49 IOs on dataset ASSO

Notes:

  1. The message NULLDESC indicates that no descriptor values exist for this descriptor. This may happen for fields defined with option NU or NC if the field contains the null value/SQL null values for all records.
  2. The message DSPASSES shows how often the data records of the file were read. In this case the number of data storage passes is 17, i.e. the data records were reread for each descriptor, because no TEMP container was defined where descriptor values can be saved. The number of data storage passes can be reduced by defining a TEMP container. This is recommended in particular for large files, because it reduces the number of required I/O operations significantly. The ADAINV parameter SUMMARY can be used to find out which size is useful for the TEMP container.
  3. The message REMOVED shows that a temporary SORT container created by ADAINV was deleted. You can also use a persistent SORT container, which is not created and deleted by ADAINV (see ADAFRM for further details).

Example 7

adainv: dbid = 1, set_uq=10
adainv: fields
adainv: na
adainv: end_of_fields
adainv: uq_conflict=reset

The unique status is to be established for the descriptor NA in file 10 of database 1. If there is more than one ISN per descriptor value, the conflicting ISNs are written to the error log and the unique status is removed.

Example 8

adainv: dbid = 1, reset_uq=10
adainv: fields
adainv: sp

The unique status is to be removed from the descriptor SP in file 10 of database 1.

Example 9

adainv: db=33
adainv: summary=112
adainv: fields
adainv: ab
adainv: ae
adainv: s1=ap(1,1),aq(1,1),ar(1,1)
adainv: s2=ac(1,3),ad(1,8),ae(1,9)
adainv: s3=ao(2,3)

This produces the following output:
